Description OSIDB Bzimport 2025-04-16 15:02:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

arcnet: Add NULL check in com20020pci_probe()

devm_kasprintf() returns NULL when memory allocation fails. Currently,
com20020pci_probe() does not check for this case, which results in a
NULL pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue and ensure
no resources are left allocated.
